4. Replace the power supply if the fuse continues to blow and a defective PCB or short cannot be
found. See “Step 7D: Remove and Replace the Power Supply (if required)” on page 2-17.
Step 7C: Check the Power Factor Indicator and Reset Button
The front panel of APSU112 provides a Power Factor LED and Reset button. If the cabinet power
factor is exceeded by overload of PCBs, the PF LED will turn on.
➤ If the PF LED indicator turns on, press the PF reset button with a pointed tool or pencil. If the
PF LED turns off and does not turn on again it may have been turned on by a current surge
while installing a PCB while the power supply was turned-on.
➤ When a PF alarm is indicated, check that the cabinet power factor is not exceeded using
“Worksheet 7 – System Power Factor Check” on page 1-41. If the Power factor has been
exceeded relocate any PCBs that are causing the PF to be exceeded.
